Prismer Cloud is an infrastructure layer for AI agents that provides shared learning, compressed context, persistent memory, collaboration, messaging, tasks, identity, and workspaces. It is for agents and the people building or using long-running agent systems that need information and outcomes to persist across sessions. The catalogue entries provide skills, hooks, agents, instructions, and a plugin for using Prismer Cloud.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00026 | $0.02469 |
| Opus 5.5 | $0.00010 | $0.00988 |
| Sonnet 5.5 | $0.00005 | $0.00494 |
| Haiku 4.5 | $0.00003 | $0.00247 |
Grade A, and why
prismer-popular-web-designs scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 21d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
86% identical to popular-web-designs — 41 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 219 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Popular Web Designs
54 adapted brand-reference descriptions for explicitly requested HTML/CSS design work. They retain palette, typography, component, spacing and prompt examples, but are not certified current brand specifications. Use source screenshots and actual product assets when fidelity matters; local corrections intentionally override invalid or inaccessible example values.

Pair it with this skill when the user wants a thoughtfully-designed page styled after a known brand:frontend-designdrives the workflow, this skill supplies the visual vocabulary.prismer-design-md— use when the deliverable is a formal DESIGN.md token spec file, not a rendered artifact.
How to Use
- Pick a design from the catalog below
- Load it: read
templates/<site>.mdrelative to this skill directory - Use the design tokens and component specs when generating HTML
- Use a loopback-only preview or an authenticated task artifact preview
Each template includes a Prismer Implementation Notes block at the top with:
- Optional network font fallback; vendor licensed fonts for offline output
- CSS font-family stacks for primary and monospace
- Reminders to use
write_filefor HTML creation and the available browser inspection tool for verification

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
